Cristiano Ronaldo has refused to be drawn on speculation that he could return to Manchester United this summer, insisting he is happy at Real Madrid.
The 28-year-old has been tipped to rejoin United, although there have been no signs of a deal between Real and his former club being struck.
Ronaldo offered little in response when asked about the rumoured interest from United during Real's International Champions Cup campaign in the United States.
"My future? I don't know - at this moment, I'm a player of Madrid," he said. "In the future, I really don't know, but at the moment I'm good where I am."
Real manager Carlo Ancelotti revealed last week that Ronaldo is free to choose his position this season, but the Portugal international has said he is not fazed by where he plays and has paid little attention to the summer activity of rivals Barcelona.
"I don't care what Barcelona do, for me it doesn't really matter," he added. "I just focus on my team, try to do my best, try to help Madrid for its goals.
"As I said before, I'm a challenge man. Season by season it's a challenge for me, so I will try to do my best this season and try to score more than last season.
"I'm always comfortable, doesn't matter which position I play, I just want to play and help the team - that's it."
